Designed and developed various programs that encompass InfoLibria’s Content Commander, a controlling application for DynaCache and MediaMall hardware appliances.

Content Commander is part of InfoLibria’s Content Distribution Network for web objects and streaming media video files. Content Commander utilizes an Active Server Page GUI to control a set of applications that examine web sites, extract web elements and Windows Media, Real Network, and Apple QuickTime streaming media files and deliver the files to caching servers along the edge of the distribution network.

Created custom applications written in Visual Basic and Visual C++ to access a SQL Server database that utilized RPC via HTTP to report status between the various machines. Created custom Windows 2000 services written in Visual C++ with ATL, COM and TCP/IP sockets to report multicast usage via an HTTP and JavaScript heartbeat signal programmed in IE and Netscape. Created custom Visual Basic COM objects for n-tier deployment of SQL Server database middle-ware.

Assisted with the integration of the Apache web server and Microsoft Internet Security and Acceleration Server with Microsoft IIS, Windows Media Server versions 4.0 & 4.1 and RealNework’s RealServer versions 7.0 & 8.0.

Developed a Visual Basic COM object benchmarking application to determine caching thresholds for the DynaCache and MediaMall server products. The application made use of COM’s multithreading capabilities to stress test the DynaCache and MediaMall hardware and software and evaluate performance under heavy load.
